We're about:

Are you active and positive about life? And are you looking for others who are fun, fit, mature, professional, laid back, positive thinkers that are over 40 and just want to make new friends? Let's get together and work out a calendar filled with skiing, camping, hiking, snow shoeing, dancing, socializing, etc.

Due to a couple of past (and rare) incidents I added the following to the group description sometime near the middle of 2012:

The Grey Wolves is not a singles group and especially it is not a dating group. There are unmarried people and married couples in the group. Our gatherings are not about trolling for dates, sex and such. Harassing behavior is not tolerated. A wide range of activities is encouraged, but I don't allow commercial, religious, political or overtly sexual gatherings on the Grey Wolves calendar. There are plenty of other meetup groups where these things are available.

To be specific, the Grey wolves is not about joining and sending emails to people sight unseen asking for dates, asking to sell things, etc. Any sight unseen email received should be taken as a red flag and reported to the organizer. Again, this is not a dating site. If you want to examine profiles and contact people, join an actual dating site. but do not do it here.

As of Jan 26th 2013, I now require that new members be approved by a group organizer. This has been done because of some entity (I suspect it was a spamming program, not an actual person) joining the group and sending sexual spam out to people attending certain events.
